OXIDATIVE STRESS

This study looks at whether drinking a daily serving of gazpacho, a cold tomato-based soup, can improve semen quality in men with low sperm counts or poor sperm movement. Eighty men will follow a healthy Mediterranean diet for 12 weeks, with half also drinking gazpacho each day. …

This study looks at whether a daily dose of freeze-dried wild blueberry powder can improve blood sugar, blood pressure, and thinking skills in women aged 20-65 who have prediabetes and are overweight. Researchers will also check if it changes gut bacteria. The goal is to see if t…

This study tests whether drinking a ginger-based beverage every day can lower inflammation and improve markers of heart health in adults who are overweight. Researchers will measure changes in blood markers like interleukins and cholesterol over time. The goal is to see if ginger…

This study looks at whether eating wild blueberries can improve heart health, thinking skills, and gut bacteria in adults aged 45-65 with high blood pressure. Researchers will measure blood pressure, artery stiffness, and memory over time. The goal is to see if a simple diet chan…

This study looks at whether drinking haskap berry juice helps people who lift weights recover faster after an intense leg workout. Thirty adults with at least 2 years of squatting experience will drink either haskap juice or a placebo and follow a low-polyphenol diet. Researchers…

This study is testing whether taking ginger capsules every day can lower markers of inflammation, oxidative stress, and blood vessel damage in adults with excess body fat. Researchers will compare a ginger group to a placebo group over time. The study involves 50 adults aged 23 t…

This study looks at how smoking little cigars affects levels of harmful chemicals called oxidants in the body. Researchers will compare two types of little cigars (high and low oxidant) to regular cigarettes in 50 daily smokers. The goal is to understand the health risks of littl…

This study looks at how oxidative stress (a type of cell damage) in the fluid around eggs and in sperm affects embryo quality and pregnancy outcomes in couples undergoing IVF. Researchers will measure stress levels in both partners and link them to how well embryos develop and im…

This study looks at whether a single dose of apple cider vinegar can change levels of a substance called malondialdehyde (a marker of oxidative stress) in the blood of adults with obesity after a meal. Researchers will compare two groups: one that eats a standard meal with apple …

This study looks at how difficult childhood experiences and sleep problems may harm blood vessel function in young adults aged 18-29. Researchers will measure sleep quality and blood vessel health in 70 participants. Some will then join a 6-week sleep improvement program to see i…

This study is testing whether products made from Chardonnay marc (the leftover grape skins and seeds from winemaking) can improve blood vessel function and reduce oxidative stress in 5 adults with higher body weight and slightly reduced blood vessel health. The goal is to gather …

This study looks at how two common inhaled anesthetics, isoflurane and sevoflurane, affect oxidative stress (a type of cell damage) in 80 adults having gallbladder removal surgery. Participants will be randomly assigned to receive one of the two anesthetics, and researchers will …

This study looks at how breathing pure oxygen for 30 minutes changes blood flow in the brain and whether vitamin C can reduce any harmful effects. Ten healthy adults will each take part in two sessions, receiving either vitamin C or a placebo before breathing oxygen. Researchers …

This study looks at new blood markers for inflammation and oxidative stress in adults with Gaucher disease type I. Researchers want to see if these markers give extra information beyond the usual tests. The goal is to better understand the disease, not to test a new treatment.

This study looks at how changes in blood flow to the brain affect breathing during sleep in healthy adults. Researchers will measure breathing responses to low oxygen and high carbon dioxide levels under normal and low-oxygen sleep conditions. The goal is to better understand bre…

This study involves 150 people with diabetic macular edema (DME) who are either starting treatment with anti-VEGF injections or a dexamethasone implant, or have not been treated before. Researchers will measure various substances in the blood and use eye scans to see if these mar…

This study follows 30 women aged 18-70 who are having DIEP flap breast reconstruction after breast cancer surgery. Researchers will take blood samples before and after surgery to measure markers of inflammation and stress. The goal is to learn more about how the body heals and to…

This study aims to understand how exposure to heavy metals, nanoparticles, and other pollutants might lead to allergies and other health problems. Researchers will compare blood, urine, and skin test results from 280 adults—some with metal allergies, some with related health issu…

This study looks at how stressful childhood experiences may harm blood vessel function in young adults ages 18-29. Researchers will test if reducing cell stress can improve blood vessel health and response to stress. The goal is to understand the biological reasons behind this li…
